Pyramid Bracket

ABSTRACT

In cable railing systems, existing brackets that allow the connection for square/rectangular posts to curved or flat top rails are not sturdy enough to sustain, overtime, applied loads from the top rail and pulling forces from the cables. The Pyramid Bracket is the preferred connection between square/rectangular posts and the top rail tubing for cable railing and guardrail in general.

The Pyramid Bracket (PB) is a connecting piece of a railing system thatattaches a square vertical post to a horizontal or inclined top rail. Itis made of two main parts: the sleeve and the saddle. The sleeve is thebottom part of the bracket that's shaped like a pyramid (hence the namePyramid Bracket) with a recessed lower area that fits into a verticalpost. The saddle is the top part of the bracket that connects the toprail to a post. The saddle connects to the sleeve by a screw whichallows it to swivel or pivot and thus accommodates inclined top rails(see FIG. 1).

The PB is suitable for many different Handrail or Guardrail Systems andstyles. The pyramid shape of the sleeve provides the PB with superiorstability and rigidity while the sleeve gives it the convenient abilityto swivel any angle. This means the PB can be used in bothhorizontal/flat situations (decks, balconies mezzanines etc.) and angledone (stairs, ramps etc.) The saddle can also be made flat or curved inorder to accommodate any shaped top rail (see FIG. 2) while keeping asturdy connection that creates better stability and safer Handrail orGuardrail Systems. The PB can be used with Handrail and guardrailsystems made of cable, glass, rod, or etc etc. but are ideal for cablesystems as they can handle applied loads from the top rail as as well asthe pulling forces of the cables over time.

Mounting the PB on top of a post can be achieved in two different ways.One is by compression fitting while using a glue (like ePoxy) on theinside sleeve. The second way is by welding the PB to the top of thePost. Grinding and Polishing is recommended after the welding processlike the case of a stainless steel post (see FIG. 3). Additionally, thePB is compatible with most solid materials (stainless steel, mild steel,aluminum, plastic, etc)

1. The Pyramid Bracket (PB) connects a square or rectangular shaped postto a square, rectangular or spherical top rail.
 2. The PB consists ofone top and one bottom part; the saddle and the sleeve. The bottompiece, the sleeve, is in the shape of a pyramid and can be secured in asquare or rectangular post. The saddle connects the top rail to a postand can either be flat or rounded to accommodate to the shape of the toprail. The two pieces are connected by a single screw which allows it topivot at an angle, making the PB applicable in a straight run (decks,balconies mezzanines etc.) or a project with any degree of angle(stairs, ramps etc.).
 3. The PB can be assembled as either a separateitem from the railing post or as one piece. As on piece the PB is weldedon the post. If in the post and the PB are two separate pieces, they canput together by compression fitting and using any steel glue (such asePoxy). The PB provides a sturdy connection, creating better stabilityfor safer guardrail, whether cable, glass, rod, or other guardrailsystem.
